octeontx: add support for OCTEON TX target
The Cavium OCTEON TX is an ARM 64-bit SoC leveraging CPU cores and periperhals from the Cavium ThunderX SoC. This initial support provides a 4.14 kernel and kernel+initramfs that is bootable on the Gateworks Newport GW630x as well as the Cavium sff8104 reference board.

Subject: [PATCH] net: thunderx: add support for rgmii internal delay modes
|
||||
|
||||
The XCV_DLL_CTL is being configured with the assumption that
|
||||
phy-mode is rgmii-txid (PHY_INTERFACE_MODE_RGMII_TXID) which is not always
|
||||
the case.
|
||||
|
||||
This patch parses the phy-mode property and uses it to configure CXV_DLL_CTL
|
||||
properly.

||||

||||

Subject: [PATCH] net: thunderx: workaround BGX TX Underflow issue
|
||||
|
||||
While it is not yet understood why a TX underflow can easily occur
|
||||
for SGMII interfaces resulting in a TX wedge. It has been found that
|
||||
disabling/re-enabling the LMAC resolves the issue.
